So the factors influencing maximum visibility are: rectangular display brightness, distance. Is greater than the minimum range, less than the range of maximum visibility, called square screen line-of-sight effectively. Best video at the same time, however, is a human sensory stadia, some people think of 40 square square big TV in the 100 metres away couldn't see, some people think is good.
